  • Systems and methods of refining natural oil feedstocks and derivatives thereof
    Patent number: 9328055
    Abstract: Systems and methods are disclosed for refining natural oil feedstocks. In some embodiments, the methods comprise transesterifying glycerides in a natural oil feedstock to provide a transesterified product comprising monounsaturated fatty acid esters and polyunsaturated fatty acid esters. In some embodiments, the methods comprise separating the polyunsaturated fatty acid esters from the monounsaturated fatty acid esters (or vice versa), to provide a separated monounsaturated fatty acid ester composition having a ratio of at least 10 parts by weight of monounsaturated fatty acid esters for every 1 part by weight of polyunsaturated fatty acid esters.

  • METHODS OF REFINING AND PRODUCING FUEL AND SPECIALTY CHEMICALS FROM NATURAL OIL FEEDSTOCKS
    Publication number: 20140336398
    Abstract: Methods are provided for refining natural oil feedstocks. The methods include reacting the feedstock with a low-molecular-weight olefin or mid-weight olefin in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product including olefins and esters. In certain embodiments, the methods further include separating the olefins from the esters in the metathesized product. In certain embodiments, the methods further include transesterifying the esters in the presence of an alcohol to form a transesterified product.
